Like in Second Life.
But that wont happen since it would make it possible for user to really abuse this feature and teleport from one to another map and troll and what so ever.
This is also the reason why you cant see all the users online on the minnimap but just your friendet ones. To avoid stress, abuse and stalking/trolling.
It can make trolling happen like, a person trolling a user then teleporting to another place or map. Though, without collectible Items... Its probably not gonna happen.
